Natalie Portman says hitting Chris Hemsworth was "one small slap for womankind."
The actress, who reprises her role as Jane Foster in "Thor: The Dark World," gives the superhero a smack in the Marvel sequel.
"Thor: The Dark World" has its world premiere in London Tuesday and is out in U.S. cinemas Nov. 8.
At a promotional event on Saturday, Portman said that she channeled all her single girlfriends: "You hear all these stories about guys and it's just good to get a nice on-screen slap like 'you didn't call me back.'"
The intention may have been payback but, according to Hemsworth, the result was less so.
